AUSTIN O. BRILL, OF ZANESVILLE, OHIO.

SUSPENSION CAR-JACK.

To all whom it may concern:

Be it known that I, AUSTIN O. BRILL, a citizen of the United States ofAmerica, and resident of Zanesville, county of M uskingum, and State ofOhio, have invented certain new and useful Improvements in SuspensionCar-Jacks, of which the following is a specification.

This invention relates to improvements in car-jacks, and moreparticularly to a suspension-jack whereby the journal-boxes ofrailway-cars may be raised for effecting the removal and insertion ofthe brasses.

The object of the invention is to provide a simple, strong, durable andefficient device whereby the journal-box of a railway-car may be quicklyand conveniently raised to permit of the removal and insertion of thebrasses.

A further object is to provide a device of the character mentioned whichis adapted to be supported or sustained by the car-wheel whose brassesor bearings are to be removed, thereby avoiding or dispensing with thenecessity for securing at the roadbed a solid support or foundation suchas is required when jacks of the ordinary pedestal type are employed.

IVith these and other objects in view,'all of which will hereinafter bemade apparent, the invention finally consists in the particularconstruction, arrangement and combination of parts which willhereinafter be fully described, reference being had to the accompanyingdrawing, forming a part of this specification, in which Figure 1 is aside elevation of the invention, showing it as it appears when appliedto a car-wheel, some of the parts being shown sectioned or broken away;Fig. 2 is a section on the line 22, Fig. 1; Fig. 3 is a section on theline 33, Fig. 1; Fig. 4 is a perspective view of the suspension bracket,a portion of one arm being broken away; and Fig. 5 is a similar view ofthe cross-bar.

Referring to said drawing, in which like reference characters designatelike parts throughout the several views-1 indicates a car-wheel, 2 theaxle, 3 the journal-box, and 4 the brasses which rest upon the axlewithin the journal-box, all being of an ordinary construction.

The lifting mechanism comprises, essentially. a suspension-bracket 5adapted to engage and receive support from a car-wheel. and adjustableconnections between said Specification of Letters Patent.

bracket and the journal box whereby the latter may be elevated. Saidsuspensionbracket 5 consists of a body portion 6, a pair of divergentintegral arms 7 having hooks 8 on their outer ends adapted to clutch theflange 9 of the car-wheel I, and an integral downwardly and rearwardlyinclined leg or brace 10 adapted to rest against the face of the wheelabove and adjacent to the journal box 3.

Supported by a hand-wheel 11 whose hub rests upon the body portion 6 ofthe suspension-bracket at each side of a longitudinal slot 12 providedin said body portion is a lifting-screw 13 which is adjustable alongsaid slot, adjustment being necessary in order to adapt the device foruse in connection With journal-boxes of dilferent sizes or types. Thelower end of said lifting-screw has swiveled thereto or thereon a clevis1.4 in which is pivotally supported a cross-bar 15. Fixed to one end orsaid cross-bar is one end of a chain 16 which is adapted to be passeddown around the journal-box and have its opposite end inserted in anappropriate slot 17 provided in the opposite end of said cross-bar,where it is securely held against accidental displacement. Theemployment of a chain, such as is herein shown, whose links are soformed as to be readily gripped by the parallel members 15 formedporting engagement with the face of the wheel. In this position the twoarms 7 engage the wheel at opposite sides and at equal distances fromthe vertical median line thereof, thus effectually preventing lateralmovement or any tendency on the part of the bracket to sway. Thelifting-screw 13 is then slipped along the slot 12 to a point directlyover that part of the journal-box which is to be engaged by the chain16, and the said chain is looped around said box. Then, by turning thehand-wheel 11, who e hub is in threaded engagement with said screw, thejournal-box is raised, freeing the brasses from the weight of the car,and thus permitting the same to be removed and replaced.

mounted in a threaded hole 18 in the end of an integral extension 19 ofthe body portion 6 or the suspensioirbracket is a veFt'T cal screw 20which carries upon' its lower end a swiveled clevis 21 to which ispivoted a curved supporting-bar 22 adapted to en gage and receivesupport from the end of the car-axle 2. Said bar has its free endpointed so that it readily engages the usual socket or centering cavity2b in the end of the axle. As is apparent, this supportingbar 22 withits correlated parts serves as a brace whereby the outer end of thesupport ing-bracket 5 may be additionally braced or supported when thelatter is subjected to severe strain; however, this may be entirelyomitted, if desired. For adjusting the supporting-bar, a smallhand-wheel 24 is fixed upon the screw 20 above the swivel joint wherebythe latter may be turned to adjust its elevation.

The supporting-bracket is made heavy in order to effectually withstandthe strains to which it is subjected.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is

1. In a car journal box lifting mechanism, a supporting bracketconsisting of a body portion having a pair of divergent arms adapted toengage and receive support from a car wheel, and a brace adapted. toengage the face of the car wheel, and adjustable connections between thesupporting bracket and journal box whereby the latter can be raised.

2. In a car journal box lifting mechanism, a supporting bracketconsisting of a body portion, a pair of integral divergent arms havingsupporting hooks adapted to engage and receive support from the carwheel, and a brace adapted to engage the face of the car wheel, alifting screw supported by said bracket, means for connecting said screwto the journal box, and means whereby said screw may be raised withrelation to said bracket.

3. A car journal box lifting mechanism consisting of a pair of divergentarms adapted for supporting engagement with a car wheel on oppositesides of a vertical median line therethrough, a body formed integralwith said arms, a supporting leg, a lifting screw adjustably mounted onsaid body portion, connections between said screw and the journal boxwhereby the latter is raised when said screw is raised, and means forelevating said screw.

4. A car journal box lifting mechanism consisting of a pair of divergentarms adapted for supporting engagement with a car wheel on oppositesides of a vertical median line therethrough, a body formed integralwith said arms, a supporting leg, a lifting screw supported by said bodyportion, con nections between said screw and the journal box whereby thelatter is elevated when said screw is raised, means for elevating saidscrew, and means carried b the outer end of said bracket and adapte toreceive support from the car axle whereby said outer end of the bracketis braced.

5. A car journal box lifting mechanism consisting of a pair of divergentarms adapted for supporting engagement with a car wheel on oppositesides of a vertical median line therethrough, a body formed integralwith said arms, a supporting leg, a lifting screw adjustab]. supportedby said body portion, connections between said screw and the journal boxwhereby the latter is elevated when said screw is raised, means forelevating said screw, a second adjustable screw carried by the bracket,and a supporting bar connected to said screw and adapted to engage thecar axle for bracing the outer end of said bracket.

6. In a device of the character described, the combination with abracket adapted to receive support from a car wheel, and journal boxliftingmechanism sustained by said bracket, of bracing means for theouter end of said bracket, said bracing means comprising a screw whichis vertically adjustable with relation to said bracket, and a curvedsupporting bar swiveled to said screw and adapted to engage thecentering cavity in the'car axle.

In testimony whereof I aflix my signature in presence of two subscribingwitnesses.

AUSTIN o. BRILL.
